The original band of frequencies produced by a transducer, such as a microphone, telegraph key, or other signal-initiating device, prior to initial modulation. Note 1: In transmission systems, the baseband signal is usually used to modulate a carrier. Note 2: Demodulation re-creates the baseband signal. Note 3: Baseband describes the signal state prior to modulation, prior to multiplexing, following demultiplexing, and following demodulation. Note 4: Baseband frequencies are usually characterized by being much lower in frequency than the frequencies that result when the baseband signal is used to modulate a carrier or subcarrier. 2. In facsimile, the frequency of a signal equal in bandwidth to that between zero frequency and maximum keying frequency.
Industry:Telecommunications
The organizations, personnel, procedures, facilities, and networks employed to transmit and receive information by electrical or electronic means. Note 1: Telecommunications facilities include, but are not necessarily limited to, terrestrial radio, metallic and optical fiber cables, artificial Earth satellite communications, radio and television stations (traditional broadcast as well as cable and satellite broadcast,) public switched telephone network (s,) etc. Note 2: Examples of advanced telecommunications infrastructure facilities are direct broadcast satellite (DBS,) digital audio broadcasting (DAB,) Advanced Digital Television, and the Global Positioning System (GPS,) which is used extensively for precise navigation and timing.
